Let me repeat myself.
1. We can't even convince many of your ideology to even accept that there IS a problem. Many countries have no capacity to offer much help, if they do believe and agree.
2. What gives us the right to "force" measures to address AGW upon anybody else? Why would we even want to?
3. We have always been more successful at using persuasion, economic leverage, incentives, etc. and lead from the front. It is impossible to herd cats. But if you have a fish, they will all follow you.
